The media could not be loaded. Please make sure you read this before you buy.The ones I got were the 9.25 inches which fit most of my hard cover books so please make sure you are measuring your books before purchasing. The size is spot on so if you need to cover your 9.25 inches hardcover books I highly recommend this. Putting it on was fairly easy. The sleeve was really easy to put on. Now, if you ask me, this is a steal because $10 for 100 covers!! It is totally worth it. I see a lot of people saying that they don’t like the quality because is really thin, but this is my opinion, it is just right why it still protect the book from water in minimal scratches so in my book this is a win. The cover was built to protect the book and that’s exactly what it does. The quality is good. Another thing I would like to let you know it to align the sleeve when you’re gonna peel the tape a line Your sleeve where it needs to be because once that tape touches the plastic that’s it. Yes it is that sticky. You try to appeal it if you make a mistake, it’s gonna look all warped and weird so align before you stick. Well, hope this helps you

The material I received rips very easily. No matter which way I tried to wrap the book the material would slit right away. I figure try maybe using a smaller book to see if it was just the sizing? It didn't change anything. I also couldn't use the material for a different size book (for example a smaller size). It would have an awkward score right down the middle and it would also just rip easily.I am not impressed with the material. I would have returned it, but it was just a bother.

Once I learned how to put on the two piece cover, I was/am pleased with the product. I would like to find more sizes available.

The size was smaller than stated, 4 inches by 6 inches. The quality was low quality as they tore very easy. Was not able to use. Do not stick without tape.

I got these for my light novel, manga and manhua books. I'd say they are slightly taller then most of the books I have which I just taped and tried to fit, length from cover to cover was fine, if you need a good idea of the side the larger pieces will cover a letter sized piece of paper and fold slightly over to the back with a tiny bit of space on the sides.They are not "real thick" and they can crinkle and crease easily before application. I'd say more for display protection then heavy use. They are no where near the quality school or public librarys use.

These are very easy covers for paperbacks and they do the job. The covers are very easy to install and they protect the book well. The covers are in two pieces and go on the book easily. I was impressed that the covers come in various sizes so that you have access to a cover from pocket book size to large coffee table books. This is definitely a great addition for anyone who has, collects, maintains and just loves books but likes them to stay as new as possible.

I liked them very much. I put them on all my books before I go to any author event. While it is always better to have hardbacks, as they last longer... the paperbacks are so much improved by adding just a bit of fluff... Ann, BooksbyAFoster

They are worthless. They do not fit the book size they are advertised for. THEY ARE A WASTE OF MONEY.
